Description
in single mode or parallel mode.
Matches the system capacity.
Set this parameter based on load
capacity and redundancy
requirements.
UPS working mode
In ECO mode, when the
difference between the bypass
voltage and the rated voltage is
greater than this value, the
system determines that the ECO
voltage is abnormal and transfers
to normal mode.

Set this parameter to
Standard BSC mode for a
dual-bus system.
 After setting this parameter to
Standard BSC mode, you
need to set the two UPS
systems in the dual-bus
system to BSC master
system and BSC slave
system respectively in the
BSC master/slave system
setting. (The two UPS
systems cannot be BSC
master systems or BSC slave
systems at the same time. If
you need to change the
settings in the future, perform
operations under the guidance
of maintenance engineers.)
Specifies the rack air filter
maintenance interval. If it is set
to 0, there is no reminder.
The short-distance battery
temperature sensor monitors the
ambient temperature near
batteries, and ensures that
batteries work reliably and
securely.
